Road is equipped with several rubber rings between self-lubricating body and piston only, rubber ring is axially placed equidistant with along piston only, and two is adjacent
Form oil storage tank between rubber ring, the tail portion of piston only is additionally provided with the spacing ring contradicted with self-lubricating body, spacing ring it is outer
Peripheral wall is equipped with several limit card slots for installing sealing ring.
The utility model is further arranged to：The self-lubricating body is also set on the outer wall of piston body head position
There are annular groove, annular groove to be equipped with several oil return holes being connected to piston hole, oil return hole is arranged with piston only axle center circular array.
The utility model is further arranged to：It is equipped with deflector hole close to one end of annular groove on the oil return hole, deflector hole is in
Pyramidal structure.
The utility model is further arranged to：Several gas being placed between two adjacent oil return holes are additionally provided on the annular groove
Hole.
The utility model is further arranged to：The self-lubricating body uses the material of iron-based oiliness bearing.
It is had the following advantages by using above-mentioned technical proposal：By the structure design of self-lubricating body, make first piston
Outer wall have self-lubricating effect, improve wearability；Rubber ring is set by adding between self-lubricating body and piston only, is improved
The damping effect and its stress intensity of first piston；By forming oil storage tank between two adjacent rubber rings, to self-lubricating body
Continue fuel feeding, further increases self-lubricating effect；By the design of spacing ring and limit card slot, increase the close of first piston tail portion
Feng Xing avoids lubricating oil from being flowed out from the tail portion of first piston.

Specific implementation mode
A kind of self-lubricating first piston embodiment of the utility model is described further referring to Fig.1.
The head of a kind of self-lubricating first piston, including piston only 1, piston only 1 is equipped with piston hole 2, piston only 1
Tail portion be equipped with bulb hole 3, it is characterised in that：The outer wall of the piston only 1 is equipped with self-lubricating body 4, self-lubricating body 4
Several micropores are equipped with, several micropores form the asphalt channel of connection, are equipped between self-lubricating body 4 and piston only 1 several
Rubber ring 5, rubber ring 5 are axially placed equidistant with along piston only 1, and oil storage tank 6, piston only 1 are formed between two adjacent rubber rings 5
Tail portion be additionally provided with the spacing ring 7 contradicted with self-lubricating body 4, the periphery wall of spacing ring 7 is equipped with several for installing sealing
The limit card slot 8 of ring.
Piston only 1, rubber ring 5 and self-lubricating body 4 overlap successively from the inside to the outside, form similar traditional rubber and serve as a contrast
Set, rubber ring 5 use high-temperature resistant rubber material, and it is anti-that rubber ring can increase the damping between piston only 1 and self-lubricating body 4
Effect, piston only 1 is pressed to use traditional metal materials, it is ensured that the outer wall of structural strength, self-lubricating body 4 belongs to rubbing surface, meeting
It contradicts and rubs with cylinder inner wall, self-lubricating body 4 preferably uses the material for making iron-based oiliness bearing, iron-based oiliness bearing
Material can directly buy acquisition in market, which is using iron-based powder as primary raw material, with the burning of powder metallurgic method making
Knot body has enough intensity in performance, and material internal has countless small holes, can more freely adjust in the fabrication process
The technical advantage such as quantity, size, shape and the distribution of hole, not only can be with trapped fuel, but also can form small and tortuous oil
Paths are immersed first piston into lubricating oil using preceding, so that Lubricating Oil is permeated and are filled in oil storage tank 6, when work,
Lubricating oil can be spilled over to 4 outer wall of self-lubricating body, play self-lubricating function, can absorb lubricating oil when being stopped again, to carry
High-wearing feature prolongs the service life, and spacing ring 7 is to play position-limiting action to self-lubricating body 4, is improved to self-lubricating body 4
Fixed function, second is that by sealing ring avoid oil from the tail portion of first piston flow out.
